Document Summary
Learning: relatively enduring change in behaviour due to experience. He stated that reflexive responses are associated with cues. He pushed for behaviour to be the main topic in psychology. Habituation: decrease in behavioural responding to a repeated stimulus (not feeling your clothes on your body as it is irrelevant information) Sensitization: increase in behavioural responding to a repeated stimulus (true when a stimulus is rewarding or aversive) Operant conditioning: learning that a behaviour leads to a particular outcome. Long-term potentiation: the strengthening of synaptic connections between neutrons. 20% of soldiers were heroin addicts (compared to 0. 3% of the general population) They were sent to clinics to dry out. Relapse rate was 5% (compared to 20% in general population) Case study #2 - what causes enigmatic opiate overdose. Drug tolerance: the longer you take a drug, the more you need to take. Testing someone in the same environment leads to tolerance as they expect the cues.
